In the process of selecting mbbr plastic biological media, it is necessary to consider the content of solid particles in the suspension, the distribution range of the particle size during use, the influence of the media on the degree of clarification of the filtrate and the filtration rate. In addition, it also involves the selection of filtration equipment, the corrosiveness of the filtrate, and the temperature and pressure of the filtration operation.
The so-called trapping capacity of mbbr plastic biological media is the smaller particle size that can be trapped. The ability to capture depends on the pore size and distribution of the medium itself. The table below shows the smaller particles that can be captured by various types of filter media.
The permeability of the filter media reflects its resistance to filtrate flow, which affects the filter's production strength and filtration thrust force differential. The permeability of the filter media is related to the porosity of the media itself.
The slag-removing capacity of the mbbr plastic biological media refers to the ability to remove the filter cake from the surface of the medium by means of the filter cake's own strategy or compressed air blowing, mechanical scraping, etc. after filtering, which is like rotating drums, turning over, Continuous filters such as belt vacuum filters are a prerequisite for maintaining normal operation. During the filtration process, a small amount of filter residue particles are blocked in the pores of the medium. The particles must be washed away from the surface of the medium and the pores by washing, purging, etc. after the end of the unloading process in each operation cycle to maintain the filtration efficiency of the medium. And performance. The regeneration performance mainly depends on the constituent materials of the filter medium and the weaving and processing methods (manufacturing processes).www.hy-sewagetreatment.com
